    // * explicit async pauses, created by calling `assert.async()`,
    // * implicit async pauses, created when `QUnit.test()` or module hook callbacks
    //   use async-await or otherwise return a Promise.
    //
    // Happy scenario:
    //
    // * Pause is created by calling internalStop().
    //
    //   Pause is released normally by invoking release() during the same test.
    //
    //   The release() callback lets internal processing resume.
    //
    // Failure scenarios:
    //
    // * The test fails due to an uncaught exception.
    //
    //   In this case, Test.run() will call internalRecover() which empties the clears all
    //   async pauses and sets the cancelled flag, which means we silently ignore any
    //   late calls to the resume() callback, as we will have moved on to a different
    //   test by then, and we don't want to cause an extra "release during a different test"
    //   errors that the developer isn't really responsible for. This can happen when a test
    //   correctly schedules a call to release(), but also causes an uncaught error. The
    //   uncaught error means we will no longer wait for the release (as it might not arrive).
    //
    // * Pause is never released, or called an insufficient number of times.
    //
    //   Our timeout handler will kill the pause and resume test processing, basically
    //   like internalRecover(), but for one pause instead of any/all.
    //
    //   Here, too, any late calls to resume() will be silently ignored to avoid
    //   extra errors. We tolerate this since the original test will have already been
    //   marked as failure.
    //
    //   TODO: QUnit 3 will enable timeouts by default <https://github.com/qunitjs/qunit/issues/1483>,
    //   but right now a test will hang indefinitely if async pauses are not released,
    //   unless QUnit.config.testTimeout or assert.timeout() is used.
    //
    // * Pause is spontaneously released during a different test,
    //   or when no test is currently running.
    //
    //   This is close to impossible because this error only happens if the original test
    //   succesfully finished first (since other failure scenarios kill pauses and ignore
    //   late calls). It can happen if a test ended exactly as expected, but has some
    //   external or shared state continuing to hold a reference to the release callback,
    //   and either the same test scheduled another call to it in the future, or a later test
    //   causes it to be called through some shared state.
    //
    // * Pause release() is called too often, during the same test.
    //
    //   This simply throws an error, after which uncaught error handling picks it up
    //   and processing resumes.

     * - object

     *   calling an undefined function) during a "todo" test do NOT result in
     *   a failed test run.
     *
     * - If we're anywhere outside a test (be it in early event callbacks, or
     *   internally between tests, or somewhere after "runEnd" if the process is
     *   still alive for some reason), then send an "error" event to the reporters.
